 Abstract

Anomerism is a common feature of nearly all glycoconjugates. However, the impact of anomerism on their functional diversities has been rarely investigated. In our opinion, glycoconjugates are expected to dope into liposomes or vesicles for adjusting property or function. In this paper, we investigated comparatively the interfacial behaviour of a phospholipid separately doped with a pair of anomeric (α- or β-) galactolipid by using the Langmuir-Blodgett technique. The β-galactolipid was found to be more erective than the α-counterpart at the air-water interface. The molecular interaction of the α-galacto-monolayer might be stronger than the β-counterpart. Results showed an unprecedented observation that anomerism can largely impact the properties of glycolipid embedded phospholipid monolayers. The intermolecular interaction and phase state of the mixed membranes had significant influence on their interfacial behaviours. This study offers a useful insight into the more sophisticated development of these functional glyco-materials.
